Sig/Awakening in Knight Crystals

Can you guys consider adding 4* Sig / Awakening programs to T3 Knight Crystals? Even a low chance would be something. Some sort of avenue to collect these outside of purchasing would be nice, and Knight Crystal rewards are getting a bit stale and outdated as it stands.

With that in mind, it would also be nice to see Knight Crystals or some equivalent in the spotlight missions. Especially considering that Expert doesn't have any 4* crystal reward and we get an "ultimate" crystal there instead, it seems like it would offer some sort of high end potential at a low reward rate, which I would think Kabam could fit in to the spotlight rewards without them being enhanced too terribly much.
